Higher Order Modulation Explained, QPSK, 16-QAM, 64-QAM

Very thankful cuz this is a concept that people seldom discuss and analyze. After watching dozens of videos, this is the clearest version and it helps a lot, thank you, professor!

First of all great video. I'm happy to see it confirmed for me that DP-QPSK is what 100G generally uses. I see in my job 100G LR transceiver signals channelised into four lanes I assume corresponds to DP-QPSK. Baud rate=symbol rate is another key concept to get. Higher order modulation schemes fit more BITS into each SYMBOL. Maybe it's just me although I find it takes a while to find information on all these concepts and fit the good explanations together.

Great explanation by the professor! thanks you

You are welcome, Esteban. Let me know if you have other topics. It's hard to get his time, so no guarantees, but I can try. We also have a bunch of content that is already recorded that I might be able to publish, if I know there is a need. Thanks, -John Houghton

Thank you .. do we use these phase modulation on fiber when we use ethernet ? If not then why ?
